RESUMO
Residual substances that are considered hazardous to the recipient must be removed from final cellular therapeutic products manufactured for clinical purposes. In doing so, quality rules determined by competent authorities (CAs) for the clinical use of tissue- and cell-based products can be met. In our study, we carried out residual substance analyses, and purity determination studies of trypsin and trypsin inhibitor in clinically manufactured bone marrow-derived mesenchymal stromal/stem cell products, using the sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) method. Despite being a semiquantitative method, SDS-PAGE has several benefits over other methods for protein analysis, such as simplicity, convenience of use, and affordability. Due to its convenience and adaptability, SDS-PAGE is still a commonly used method in many laboratories, despite its limits in dynamic range and quantitative precision. Our goal in this work was to show that SDS-PAGE may be used effectively for protein measurement, especially where practicality and affordability are the major factors. The results of our study suggest a validated method to guide tissue and cell manufacturing sites for making use of an agreeable, accessible, and cost-effective method for residual substance analyses in clinically manufactured cellular therapies.
RESUMO
BACKGROUND AIMS: The marketing authorization of Advanced Therapy Medicinal Products (ATMPs) in Brazil is recent. The features of these therapies impose specialized regulatory action and are consequently challenging for developers. The goal of this study was to identify the industry's experience in clinical development, marketing authorization and access to ATMPs through the Unified Health System (SUS, acronym in Portuguese), from a regulatory perspective. METHODS: A survey containing structured questions was conducted among research participants who work at companies that commercialize ATMPs. A descriptive analysis was performed. RESULTS: We invited 15 foreign pharmaceutical companies, of which 10 agreed to participate. Overall, participants assessed that Brazil has a well-established regulatory system, especially the sanitary registration by the National Health Surveillance Agency (Anvisa), which ensures the quality, safety, and efficacy of the products. The Agency's good interaction with the regulated sector, the harmonization of sanitary and ethical assessment systems with other countries, and the analysis time in the biosafety assessment of Genetically Modified Organisms (GMOs) stand out as positive in industry's evaluation. On the other hand, it is important to advance the pricing regulation for these products since Brazilian regulations do not establish specific criteria for ATMP. One of the biggest challenges is the difficulty for the SUS in reimbursing these very high-cost therapies, especially using current Health Technology Assessment (HTA) methods. CONCLUSIONS: Considering the increasing number of approvals of cell and gene therapies in Brazil in the coming years, a close dialogue between the industry and the public sector is recommended to advance regulatory improvements (pricing and HTA). Additionally, the construction of policies to promote the national Health Economic-Industrial Complex, based on a mission-oriented vision that encourages innovative models of financing, especially those that consider risk-sharing and co-financing technologies, will help provide the population with universal, equitable and sustainable access to ATMP in the SUS.

Advanced therapy medicinal products (ATMPs) are rapidly evolving to offer new treatment options. The scientific, technical, and clinical complexities subject drug regulatory authorizes to regulatory challenges. To advance the regulatory capacity for ATMPs, the National Medical Products Administration in China made changes to the drug regulatory system and developed regulatory science with the goal of addressing patient needs and encouraging innovation. This study aimed to systematically identify the regulatory evidence on ATMPs in China under the guidance of an overarching framework from the World Health Organization Global Benchmarking Tool. It was found that China's administrative authorities at all levels have issued a number of policy documents to promote the development of ATMPs, covering biopharmaceutical products research and development (n = 14), biopharmaceutical industry development (n = 9), high-quality development of medical institutions (n = 1), specific development plans/projects (n = 6) and specific regional development (n = 4). The legal and regulatory framework of ATMPs in China has been established and is subject to continuous adjustment in various aspects including regulations (n = 3), departmental rules or administrative normative documents (n = 22), and technical guidance (n = 15). As the regulatory reform continues, the drug review processes have been revised, and various technical standards have been launched, which aim to establish a regulatory approach that oversees the full life-cycle development of ATMPs in the country. The limited number of investigational new drug applications and approved ATMPs suggests a lag remains between the translation of advanced therapeutic technologies into clinically available medical products. To accelerate the translational research of ATMP in countries such as China, developing and adopting real-world evidence generated from clinical use in designated healthcare facilities to support scientific decision-making in ATMP regulation is warranted. The enhancement of regulatory capacity building and multi-stakeholder collaborations should also be encouraged to facilitate the timely evaluation of promising ATMPs to meet more patient needs.

BACKGROUND AIMS: The relationship between blood establishments and advanced cellular therapies is evident in several European countries, with some involved in research and development and/or in manufacturing. The aim of the present study was to understand the advanced therapy medicinal product (ATMP) infrastructural, regulatory and logistic requirements needed for the Irish Blood Transfusion Service to support advanced therapeutics in Ireland. METHODS: An online survey consisting of 13 questions was distributed in a targeted manner to the identified ATMP stakeholders in Ireland, namely those working in industry, health care, regulatory agencies or education. Subject matter experts in the field were approached and interviewed to gain further insight into the relationship between blood and tissue establishments (BTEs) and ATMPs, to explore the advantages these institutions have in development and to highlight potential challenges for implementation. RESULTS: In total, 84.9% of survey respondents stated that BTEs have a role in the development of advanced therapeutics. Key BTE services identified as applicable to the ATMP sector from both surveys and interviews include the provision of starting materials for research and manufacturing, donor management, use of existing quality and traceability frameworks, product logistic strategies and Good Manufacturing Practice. Challenges for BTE expansion into the sector currently include high costs associated with ATMPs, lack of expertise in these therapies, limited therapeutic populations and no national ATMP strategic plan for Ireland. CONCLUSIONS: Blood establishments have services and expertise that can be extended into the advanced therapy sector. The existing knowledge and skill base of BTEs in Ireland should be leveraged to accelerate the development of ATMP strategies for industry and healthcare.

BACKGROUND: The manufacturing processes of plasma products include steps that can remove prions. The efficacy of these steps is measured in validation studies using animal brain-derived prion materials called spikes. Because the nature of the prion agent in blood is not known, the relevance of these spikes, particularly with steps that are based on retention mechanisms such as nanofiltration, is important to investigate. STUDY DESIGN AND METHODS: The aggregation and sizes of PrPres assemblies of microsomal fractions (MFs) extracted from 263K-infected hamster brains were analyzed using velocity gradients. The separated gradient fractions were either inoculated to Tg7 mice expressing hamster-PrPc to measure infectivity or used in Protein Misfolding Cyclic Amplification for measuring seeding activity. The collected data allowed for reanalyzing results from previous nanofiltration validation studies. RESULTS: A significant portion of MFs was found to be composed of small PrPres assemblies, estimated to have a size ≤24 mers (~22-528 kDa), and to contain a minimum of 20% of total prion infectivity. With this data we could calculate reductions of 4.10 log (15 N), 2.53 log (35 N), and 1.77 log (35 N) from validation studies specifically for these small PrPres objects. CONCLUSION: Our gradient data provided evidence that nanofilters can remove the majority of the smallest PrPres entities within microsomes spikes, estimated to be in a size below 24 mers, giving insight about the fact that, in our conditions, size exclusion may not be the only mechanism for retention nanofiltration.

Mitochondria's role as engines and beacons of metabolism and determinants of cellular health is being redefined through their therapeutic application as "Living Drugs" (LDs). Artificial mitochondrial transfer/transplant (AMT/T), encompassing various techniques to modify, enrich, or restore mitochondria in cells and tissues, is revolutionizing acellular therapies and the future of medicine. This article proposes a necessary definition for LDs within the Advanced Therapeutic Medicinal Products (ATMPs) framework. While recognizing different types of LDs as ATMPs, such as mesenchymal stem cells (MSCs) and chimeric antigen receptor T (CAR T) cells, we focus on mitochondria due to their unique attributes that distinguish them from traditional cell therapies. These attributes include their inherent living nature, diverse sources, industry applicability, validation, customizability for therapeutic needs, and their capability to adapt and respond within recipient cells. We trace the journey from initial breakthroughs in AMT/T to the current state-of-the-art applications by emerging innovative companies, highlighting the need for manufacturing standards to navigate the transition of mitochondrial therapies from concept to clinical practice. By providing a comprehensive overview of the scientific, clinical, and commercial landscape of mitochondria as LDs, this article contributes to the essential dialogue among regulatory agencies, academia, and industry to shape their future in medicine.

AIMS: To conduct a single-arm open-label feasibility trial of the safety and tolerability of a full-spectrum cannabidiol (CBD)-dominant cannabis-based medicinal product for treating the symptoms of long COVID. METHODS: The treatment phase ran for a total of 21 weeks, followed by ~3 weeks without the study drug. Participants received up to 3 mL of MediCabilis 5% CBD Oil (50 mg CBD/mL, <2 mg δ-9-tetrahydrocannabinol/mL) per day orally. Monthly patient-reported outcome measures of common symptoms and daily self-report of symptoms were collected via a smartphone app. Key measures of heart rate, activity, sleep and oxygen saturation were assessed using wearable technology. RESULTS: Twelve (1 male, 11 female) individuals diagnosed with long COVID were recruited into the trial. All participants adhered to the treatment protocol for the duration of the study and there were no serious adverse events. Response rates for the research assessments were high with over 90% completion of patient-reported outcome measures and daily self-report. CONCLUSION: The study drug was safe and well-tolerated, demonstrating feasibility of CBD-dominant cannabis-based medicinal products in individuals diagnosed with long COVID. However, there were limitations in research design related to recruitment strategy demonstrating a lack of feasibility in the approach implemented in this study. Future work with larger samples and incorporating a control group are required to test the efficacy of this treatment.

OBJECTIVES: Health technology assessment (HTA) of advanced therapy medicinal products (ATMPs), such as high-cost and one-time cell and gene therapies, is particularly challenging. Outcomes-based agreements (OBAs) are a potential solution to mitigate the risks while providing access to patients but are not widely used across Europe. This study aimed to develop policy recommendations to support the acceptability and implementation of OBAs in Europe. METHODS: A policy sandbox approach was used to engage with stakeholders and explore how HTA organizations can support reimbursement decisions regarding OBAs for ATMPs. A panel of 38 experts from across the European region was convened in 2 workshops, representing payers, HTA organizations, patients, registries, and an industry trade body. RESULTS: Policy recommendations were developed to support the appropriate consideration of OBAs for reimbursing highly uncertain technologies, such as ATMPs. If a positive HTA recommendation cannot be made at the proposed price, then a simple price discount reflecting the uncertainty is preferred over complex solutions such as OBAs. If an OBA is pursued, it should be designed collaboratively with all stakeholders to understand data collection feasibility and minimize burden to patients and providers. Payers are encouraged to approach OBAs as a tool for informed decision making, including a readiness to make negative reimbursement decisions based on unfavorable evidence. CONCLUSIONS: The study presents a policy framework for using OBAs in reimbursement decisions. OBAs must be carefully designed, focusing on appropriateness and the burden of implementation. The relevant authorities should be committed to making decisions in light of the resulting evidence.
RESUMO
Plasma-derived medicinal products (PDMPs) are essential in the treatment of acute and chronic life-threatening diseases. The Korea Ministry of Food and Drug Safety has conducted a national lot release (NLR) of PDMPs since 2012 based on a summary protocol review system and lot release testing. However, few studies have investigated the performance or characteristics of the NLR framework. Over the past decade, the NLR of PDMPs was approximately 1000 per year, including mainly albumins, immunoglobulins, fibrin sealant kits, and coagulation factors, among others. The NLR system for PDMPs is similar to that for vaccines, except that PDMPs are manufactured using human plasma, which requires strict safety management. This study describes the status of NLR procedures for PDMPs and outlines the regulatory requirements needed to safely manage plasma for fractionation in Korea. This study can aid national control laboratories and marketing authorization holders in developing regulatory systems that assure the availability of safe and effective PDMPs.

Advanced therapy medicinal products (ATMPs) are among the most complex pharmaceuticals with high human specificity. Species differences severely limit the clinical relevance of in vivo data. We conducted interviews with stakeholders involved in ATMP development about their perspective on the use of in vivo studies, the perceived hurdles and associated potential solutions regarding non-clinical development of ATMPs. In total, 17 stakeholders from 9 different countries were interviewed. A workshop was held with key stakeholders to further discuss major topics identified from the interviews. Conducting in vivo studies remains the status quo for ATMPs development. The hurdles identified included determining the amount of information required before clinical entry and effective use of limited human samples to understand a treatment or for clinical monitoring. A number of key points defined the need for future in vivo studies as well as improved application and implementation of New Approach Methodology (NAM)-based approach for products within a well-known modality or technology platform. These included data transparency, understanding of the added value of in vivo studies, and continuous advancement, evaluation, and qualification of NAMs. Based on the outcome of the discussions, a roadmap with practical steps towards a human-centric safety assessment of ATMPs was established.

In France, blood donations are tested in pools of 96 samples for parvovirus B19 (B19V) DNA to discard plasma for fractionation when it contains high viral loads. Between January 2015 and March 2024, B19V-positive donations decreased during the COVID-19 pandemic, followed by a strong rebound in 2023 and unusually high circulation during winter 2023/24 (ca 10 times higher December 2023-March 2024 vs the pre-pandemic period). Variations over time are probably related to measures implemented to limit SARS-CoV-2 spread.

Mesenchymal stromal cell (MSC)-based advanced therapy medicinal products (ATMPs) are being tried in a vast range of clinical applications. These cells can be isolated from different donor tissues by using several methods, or they can even be derived from induced pluripotent stem cells or embryonic stem cells. However, ATMP heterogeneity may impact product identity and potency, and, consequently, clinical trial outcomes. In this review, we discuss these topics and the need to establish minimal criteria regarding the manufacturing of MSCs so that these innovative therapeutics may be better positioned to contribute to the advancement of regenerative medicine.

Extracellular vesicles (EVs) hold great promise for clinical application as new diagnostic and therapeutic modalities. This paper describes major GMP-based upstream and downstream manufacturing processes for EV large-scale production, also focusing on post-processing technologies such as surface bioengineering and uploading studies to yield novel EV-based diagnostics and advanced therapy medicinal products. This paper also focuses on the quality, safety, and efficacy issues of the bioengineered EV drug candidates before first-in-human studies. Because clinical trials involving extracellular vesicles are on the global rise, this paper encompasses different clinical studies registered on clinical-trial register platforms, with varying levels of advancement, highlighting the growing interest in EV-related clinical programs. Navigating the regulatory affairs of EVs poses real challenges, and obtaining marketing authorization for EV-based medicines remains complex due to the lack of specific regulatory guidelines for such novel products. This paper discusses the state-of-the-art regulatory knowledge to date on EV-based diagnostics and medicinal products, highlighting further research and global regulatory needs for the safe and reliable implementation of bioengineered EVs as diagnostic and therapeutic tools in clinical settings. Post-marketing pharmacovigilance for EV-based medicinal products is also presented, mainly addressing such topics as risk assessment and risk management.

The conduct of clinical trials of investigational medicinal products brings, in clinical research with the participation of human subjects, various ethical concerns, which should be competently addressed. In clinical research, adherence to ethical principles plays an essential role in the safety of clinical trial participants, as well as in minimizing risks to the integrity and validity of data collected and analyzed during the conduct of clinical trials. The article contains an overview of the most important legal regulations and ethical standards that regulate the field of clinical trials. Furthermore, the paper focuses on some of the most important ethical aspects representing potential risk areas during clinical trials. The article also presents two case studies in which investigational medicinal products were not applied in compliance with the clinical trial requirements and which provide insight into the potential ethical implications that may occur when clinical trials of human medicinal products are performed incorrectly.
RESUMO
Mesenchymal stem cells (MSCs) have been studied for their potential benefits in treating acute respiratory distress syndrome (ARDS) and have reported mild effects when trialed within human clinical trials. MSCs have been investigated in preclinical models with efficacy when administered at the time of lung injury. Human integrin α10ß1-selected adipose tissue-derived MSCs (integrin α10ß1-MSCs) have shown immunomodulatory and regenerative effects in various disease models. We hypothesized that integrin α10ß1 selected-MSCs can be used to treat a sepsis-induced ARDS in a porcine model when administering cells after established injury rather than simultaneously. This was hypothesized to reflect a clinical picture of treatment with MSCs in human ARDS. 12 pigs were randomized to the treated or placebo-controlled group prior to the induction of mild to moderate ARDS via lipopolysaccharide administration. The treated group received 5 × 106 cells/kg integrin α10ß1-selected MSCs and both groups were followed for 12 h. ARDS was confirmed with blood gases and retrospectively with histological changes. After intervention, the treated group showed decreased need for inotropic support, fewer signs of histopathological lung injury including less alveolar wall thickening and reduction of the hypercoagulative disease state. The MSC treatment was not associated with adverse events over the monitoring period. This provides new opportunities to investigate integrin α10ß1-selected MSCs as a treatment for a disease which does not yet have any definitive therapeutic options.

The development of medicinal products often continues throughout the different phases of a clinical study and may require challenging changes in raw and starting materials at later stages. Comparability between the product properties pre- and post-change thus needs to be ensured. Here, we describe and validate the regulatory compliant change of a raw material using the example of a nasal chondrocyte tissue-engineered cartilage (N-TEC) product, initially developed for treatment of confined knee cartilage lesions. Scaling up the size of N-TEC as required for the treatment of larger osteoarthritis defects required the substitution of autologous serum with a clinical-grade human platelet lysate (hPL) to achieve greater cell numbers necessary for the manufacturing of larger size grafts. A risk-based approach was performed to fulfill regulatory requirements and demonstrate comparability of the products manufactured with the standard process (autologous serum) already applied in clinical indications and the modified process (hPL). Critical attributes with regard to quality, purity, efficacy, safety and stability of the product as well as associated test methods and acceptance criteria were defined. Results showed that hPL added during the expansion phase of nasal chondrocytes enhances proliferation rate, population doublings and cell numbers at passage 2 without promoting the overgrowth of potentially contaminant perichondrial cells. N-TEC generated with the modified versus standard process contained similar content of DNA and cartilaginous matrix proteins with even greater expression levels of chondrogenic genes. The increased risk for tumorigenicity potentially associated with the use of hPL was assessed through karyotyping of chondrocytes at passage 4, revealing no chromosomal changes. Moreover, the shelf-life of N-TEC established for the standard process could be confirmed with the modified process. In conclusion, we demonstrated the introduction of hPL in the manufacturing process of a tissue engineered product, already used in a late-stage clinical trial. Based on this study, the national competent authorities in Switzerland and Germany accepted the modified process which is now applied for ongoing clinical tests of N-TEC. The described activities can thus be taken as a paradigm for successful and regulatory compliant demonstration of comparability in advanced therapy medicinal products manufacturing.

The development and production of cell gene and tissue (CGT)-based therapies requires a specialized workforce. Entering the CGT arena is complex because it involves different scientific and biomedical aspects (e.g., immunology, stem cell biology and transplantation), as well as knowledge of regulatory affairs and compliance with pharmaceutical quality standards. Currently, both industry and academia are facing a worldwide workforce shortage, whereas only a handful of educational and training initiatives specifically address the peculiarities of CGT product development, the procurement of substances of human origin, the manufacturing process itself and clinical monitoring and biovigilance. The training offered by traditional Master's and PhD programs is not suited for training a skilled workforce ready to enter the increasingly fast-growing CGT field. Indeed, typically these programs are of long duration and only partially cover the required competencies, whereas the demand for a specialized workforce relentlessly increases. In this paper, we (i) present and discuss our understanding of the roots of current growth acceleration of the CGT field; (ii) anticipate future workforce needs due to the expected increase of marketed CGT-based therapies and (iii) evaluate potential solutions that seek to adapt, develop and implement current educational and training initiatives. Importantly for these solutions, we call for scientific societies, such as the International Society for Cell & Gene Therapy, to play a more active role and act as catalysers for new initiatives, building bridges between academia and Industry to establish effective educational and training programs that will engage and prepare a new generation of qualified professionals for entry into the CGT field.

Medicine development for rare diseases, including inborn errors of metabolism (IEMs) is challenging. Many academic innovations fail to reach the patient, either by stranding in the translational stage or due to suboptimal patient access related to pricing or uncertain effectiveness. Expanding and solidifying the role of the academic in public-private partnerships (PPPs) may present an innovative solution to help overcome these complexities. This narrative review explores the literature on traditional and novel collaborative approaches to medicine development for rare diseases and analyzes examples of PPPs, with a specific focus on IEMs. Several academic institutions have introduced guidelines for socially responsible licensing of innovations for private development. The PPP model offers a more integrative approach toward academic involvement of medicine development. By sharing risks and rewards, failures in the translational stage can be mutually absorbed. If socially responsible terms are not included, however, high pricing can impede patient access. Therefore, we propose a framework for socially responsible PPPs aimed at medicine development for metabolic disorders. This socially responsible PPP framework could stimulate successful and accessible medicine development for IEMs as well as other rare diseases if the establishment of such collaborations includes terms securing joint data ownership and evidence generation, fast access, and socially responsible pricing.

OBJECTIVES: The uncertainty in the cost-benefit of advanced therapy medicinal products (ATMPs) is a current challenge for their reimbursement in health systems. This study aimed to provide a comparative analysis of the National Health Authorities (NHAs) reimbursement recommendations issued in different European countries. METHODS: The NHA reimbursement recommendations for the approved ATMPs were compared among 8 European Union (EU) Countries (EU8: Ireland, England/Wales, Scotland, The Netherlands, France, Germany, Spain, and Italy). The search was carried out until December 31, 2021. RESULTS: A total of 19 approved ATMPs and 76 appraisal reports were analyzed. The majority of the ATMPs were reimbursed, although with uncertainty in added therapeutic value. No relationship between the type of the European Medicines Agency approval and reimbursement was found. Managed entry agreements, such as payment by results, were necessary to ensure market access. The main issue during the evaluation was to base the cost-effectiveness analyses on assumptions because of the limited long-term data. The estimated incremental cost-effectiveness ratio among countries reveals high variability. Overall, the median time to NHA recommendation for the EU8 is in the range of 9 to 17 months. CONCLUSIONS: Transparent, harmonized, and systematic assessments across the EU NHAs in terms of cost-effectiveness, added therapeutic value, and grade of innovativeness are needed. This could lead to a more aligned access, increasing the EU market attractiveness and raising public fairness in terms of patient access and pricing.
